魔法抗性

Magic resistance (or MR) is a stat that all units have, including minions, monsters, and buildings. Increasing magic resistance reduces the magic damage the unit takes. Each champion begins with some magic resistance which may increase with level. You can gain additional magic resistance from abilities, items, masteries, and runes. Magic resistance stacks additively.

All champions begin with 30 base magic resistance. No ranged champions gain magic resistance per level, but many melee champions do, with 52.5 being the maximum magic resistance possible without items, runes, masteries, or ally buffs.

Every point of magic resistance requires a unit to take 1% more of its maximum health in magic damage to be killed. This is called "effective health."

Example: A unit with 60 magic resistance has 60% of its maximum health in its effective health, so if the unit has 1000 maximum health, it will take 1600 magic damage to kill it.

What this means: by definition, magic resistance does not have diminishing returns, because each point increases the unit's effective health against magic damage by 1% of its current actual health value whether the unit has 10 magic resistance or 1000 magic resistance.

Note: Unlike health, increasing magic resistance also makes healing more effective because it takes more effort to remove the unit's health than it does to restore it.

Hexdrinker: +30 magic resistance, +25 attack damage Unique passive: If you would take magic damage which would leave you at less than 30% of your maximum health, you first gain a shield which absorbs 250 magic damage for 5 seconds. 60 second cooldown. 1400 gold.

Lich Bane: +30 magic resistance, +350 mana +80 ability power +7% movement speed. Unique passive: 100% chance when an ability is used that your next physical attack deals an additional 100% of your ability power in damage. This effect has a 2 second cooldown. 3470 gold.

Maw of Malmortius: +36 magic resistance, +55 attack damage, Unique Passive: +1 Attack Damage for every 2.5% health missing, Unique Passive: If you would take magic damage which would leave you at less than 30% of your maximum health, you gain a shield which absorbs 400 magic damage for 5 seconds. 60 second cooldown 3300 gold.

格雷福斯的True GritTrue Grit increases his magic resistance by 1 / 2 / 3 every second he remains in combat. This bonus stacks up to 10 times. Graves is considered in combat if he has dealt or received damage in the last 3 seconds.

A disconnected level 18 Garen with the same items, runes, masteries and support as the above Master Yi will give a total of approximately 2144 MR after applying Courage for 95.5% reduction. Without the bonus Magic Resistance from leaving, Courage does not quite equal Meditate. This is the highest possible amount of Magic Resistance.

Unlike the Master Yi example, a similarly kitted and supported Trundle using Agony on the Garen will actually result in a reduced 1858 Magic Resistance on the Trundle.
